All market data is pinned to the June 9, 2026 close; all filings and news are dated on or before June 9, 2026. Disclosed figures come from SEC filings and company earnings releases and are treated as hard numbers. Consensus figures come from named estimate aggregators and carry their basis. Author scenarios are flagged as such in the body and in Figure 5.

Round-1 edit verifications

The take-rate in the opening (“roughly 0.27%”). Basis: combined FY2025 network net revenue ÷ combined gross dollar volume. Visa FY2025 (ended Sept 30, 2025): net revenue $40.0B ÷ total volume $16,721B (payments volume $14,217B + cash $2,504B, Q4 FY25 operational performance data) = 0.239%. Mastercard FY2025 (calendar): net revenue $32.791B ÷ gross dollar volume $10,632B (Q4’25 release operating-performance table) = 0.308%. Combined: $72.8B ÷ $27,353B = 0.266% ≈ 0.27%. Note this is the networks’ own revenue take — not the 2–3% interchange merchants pay, which goes overwhelmingly to card-issuing banks. Visa Q4 FY25 operational data · MA Q4’25 release.

History and market structure

Net margins (Figure 3). FY2025 GAAP: Visa net income $20,058M ÷ net revenue $40,000M = 50.1% (Visa FY2025 10-K, Nov 6, 2025); Mastercard $14,968M ÷ $32,791M = 45.6% (GAAP diluted EPS $16.52) (MA FY2025 10-K, Feb 11, 2026); American Express $10,833M ÷ $72,229M revenues net of interest expense = 15.0% (AXP FY2025 10-K, Feb 6, 2026). S&P 500 estimated CY2025 net profit margin 12.9% — aggregate (index-level), not median (FactSet Insight, John Butters, Dec 15, 2025).

The growth scorecard — “Mastercard has out-grown Visa in seven of the past ten years.” Reported net revenue growth, MA calendar years vs V fiscal years (Sept-end), from each company’s 10-Ks: 2016 MA +11.5% / V +8.7% (MA); 2017 +16.0% / +21.7% (V — inflated by the Visa Europe acquisition, closed June 2016); 2018 +19.6% / +12.3% (MA); 2019 +12.9% / +11.5% (MA); 2020 −9.4% / −4.9% (V — fiscal-calendar offset around COVID); 2021 +23.4% / +10.3% (MA); 2022 +17.8% / +21.6% (V — same fiscal offset on the travel rebound); 2023 +12.9% / +11.4% (MA); 2024 +12.2% / +10.0% (MA); 2025 +16.4% / +11.3% (MA). Scorecard: MA 7, V 3, with each V win carrying the noted asterisk. Note the ~3-month fiscal offset when comparing any single year.

IPOs and splits. Mastercard priced at $39.00 on May 24, 2006 (began trading May 25); 10-for-1 split distributed January 21, 2014 → $3.90 split-adjusted basis; $495.24 ÷ $3.90 = 127.0x, price-only, excludes dividends (Mastercard IPO press release, May 2006; Washington Post, May 24, 2006). Visa priced at $44 on March 18, 2008; base offering raised ~$17.86B — the largest IPO in US history at the time (with overallotment, ~$19.7B total); 4-for-1 split distributed March 18, 2015 → $11.00 basis; $325.05 ÷ $11.00 = 29.55x, price-only (CNN/Fortune, Mar 18, 2008; Visa Form 424B4).

Durbin Amendment and the 2010–2011 dress rehearsal (Figure 4). Durbin passed within Dodd-Frank, signed July 21, 2010. The Fed’s Regulation II final rule (June 29, 2011) capped covered-issuer debit interchange at 21¢ + 0.05% + 1¢ fraud adjustment, effective October 1, 2011; average interchange for covered issuers fell from ~43–44¢ (2009 average) to ~24¢ — a cut of nearly half (Fed press release, June 29, 2011; Fed interchange data, May 1, 2012; CRS R41913). Visa fell 12.7% on December 16, 2010 — the day the Fed proposed a harsher 12¢ cap — and Mastercard fell 10% ($19.235 → $16.798 split-adjusted closes, Yahoo Finance daily data; corroborated by CNN Money, Dec 16, 2010: “Shares of Visa closed nearly 13% lower… MasterCard slipped more than 10%”). Bank of America’s $5 debit fee: announced Sept 29, 2011, killed Nov 1, 2011 (CNN Money). Figure 4 basis: Visa split-adjusted closes (Yahoo Finance), indexed to 100 at the September 30, 2011 close ($21.43) — the last close before the caps took effect; endpoint December 31, 2021 close $216.71 = 10.11x price-only return, excluding dividends (measured from the October 3, 2011 close of $21.07, the multiple is 10.29x). Monthly closes plotted through 2012, quarterly thereafter; every plotted point is a verified month-end close.

BankAmericard / Visa origins. Launched September 1958 in Fresno, CA by Bank of America (the “Fresno drop”); the first widely successful general-purpose credit card with revolving credit; out-of-state licensing from 1966 created the first national bank-card network; renamed Visa in 1976. (Diners Club, 1950, was the first universal charge card.) (Britannica; Visa Inc. history).

American Express history. Founded March 18, 1850 (Buffalo, NY) as an express/freight business. November 1963 salad-oil scandal (Allied Crude Vegetable Oil / De Angelis; Amex warehousing subsidiary liable, losses >$180M). Buffett began buying in 1964, ultimately committing ~$13M — up to ~40% of Buffett Partnership assets at the position’s peak — for ~5% of the company. Berkshire Hathaway owned 151.6M shares = 22.2% of AXP as of March 31, 2026 (Berkshire Q1 2026 10-Q; salad oil scandal; Fortune, Sept 2024).

Apple Pay (2014). Announced Sept 9, 2014. Contemporary threat framing: NPR, “Apple Takes A Swipe At The Credit Card” (Sept 12, 2014); Motley Fool/Nasdaq, “Is Apple Pay Going to Kill Your Credit Card?” (Sept 28, 2014). The networks ran Apple Pay’s tokenization and earned new fees from it (PYMNTS, 2014).

Networks settling in stablecoins. Visa: first major network to settle in USDC (March 29, 2021; expanded to Solana/acquirers Sept 5, 2023) (Visa press releases). Mastercard: USDC settlement work from July 2021; live multi-stablecoin settlement (USDC, PYUSD, RLUSD and others) announced June 3, 2026 (Ledger Insights).

Consensus and multiples

Consensus EPS. MA: ~$19.65 FY2026 (stockanalysis.com forecast, 36 analysts); $23.48 FY2027 and $27.26 FY2028 (WallStreetZen — 2028 coverage is thin and rests on this aggregator). V: ~$13.14 FY2026 (Sep year-end; stockanalysis.com). AXP: ~$17.61 2026 consensus, vs management guide midpoint $17.60.

Multiples in prose (computed, basis named). MA trailing: $495.24 / $17.01 = 29.1x. MA forward: $495.24 / $19.65 = 25.2x. V forward: $325.05 / $13.14 = 24.7x (fiscal-2026 consensus). AXP: $318.38 / $17.60 guide midpoint = 18.1x.

Five-year average multiples (Figure 6). Trailing five-year average P/E: MA ≈ 36.5x (yearly trailing P/E 2021–2025: 40.9 / 33.9 / 36.0 / 37.8 / 34.2; lowest year-end finish ≈ 33.9x), V ≈ 30.5x, AXP ≈ 18.4x — Wisesheets / FullRatio. MA trailing today: $495.24 ÷ $17.01 2025 adjusted EPS = 29.1x (on GAAP 2025 EPS of $16.52 it is 30.0x). The bear scenario’s “22x — a multiple this stock hasn’t seen since 2012”: MA’s trailing P/E at every major drawdown low since bottomed at ~23x or higher (Feb 2016 ≈ 23.4x; Mar 2020 ≈ 25.2x; Jun 2026 ≈ 28x); it last traded at or below ~22x trailing in 2012 (Yahoo Finance price history ÷ prior-FY GAAP EPS from SEC XBRL).

Author scenarios (Figure 7)

Bear 22x × ~$23 of 2028 adjusted EPS (growth converging to Visa’s ~11%) ≈ $505. Base 29x (today’s trailing multiple, no re-rate) × ~$27 (consensus path) ≈ $780. Bull 34x (below the ~36x five-year average) × ~$27 ≈ $920. These are the author’s assumptions, not estimates or targets from any cited source.
